An embryo, despite the fact that it may seem of good quality due to its morphology, may have chromosomal genetic alterations that cause the embryo not to implant, leading to an abortion or the birth of a baby affected, for example, by Down syndrome.
However, it is possible to carry out a genetic test on the embryos obtained in an IVF cycle. This preimplantation genetic test (PGT-A) is especially recommended in the following situations:
- Advanced maternal age.
- Repeat abort.
- Implantation failure.
- Severe male factor.
In this way, only the embryos that have had a favorable result in the genetic study will be transferred to the woman's uterus.
